Bug 111332

Created attachment 191252 [details] Ref-test highlighting the problem In absence of CSS Regions, floats determine their width according to the width of their children, as per the spec. However, when a child of a float is a region, the float will use the width of the *content flowed in the region* as their width, effectively ignoring the width of the region itself. E.g. in the attached test case, you should see a yellow circle with a black border with a 90 degrees slice from it being black (provided you have the Ahem font installed on your machine). This circle should be entirely contained in a green rectangle. However, right now the green rectangle is as wide as the black slice (just half of the circle wide).
